[PATCH] ARM: u300: augment device tree with DMA channels

Linus Walleij linus.walleij at stericsson.com
Thu May 2 19:06:49 EST 2013


From: Linus Walleij <linus.walleij at linaro.org>

This adds DMA channel assignments to the MMC/SD-controller
and the two UARTs already in the U300 device tree, as we
have now defined a way to obtain DMA channels from the
device tree.
